5 reasons why not to buy a high end GPU
There might be a lot of different reasons why someone would want a high end graphic card, but here are top reasons.
While you might be rich, a lot of people aren't. Still this doesn't mean that you have the money and you should buy the card. A lot of cards are overpriced, especially those of new generations or the top cards of each manufacturer, AMD and Nvidia. Still, this is the most important part a lot of people try to avoid.
Being irritating at times, temperatures of high end cards are usually capable of achieving 100 degree Celsius, thus getting damaged. A typical temperature for computer hardware would be 80 degrees at max. If your card goes over that, your capacitors and other parts might explode, thus not only damaging your high end card, but also other computer hardware.
This is the one I personally hate the most. I would recommend getting a triple fan if you target high end graphic cards. What is even worse here, it will cost you more. Usually the noise is not irritating if you buy a triple one, but it might be a chance that if you buy a stock cooler card, it will be so noisy, it will make you destroy the card! I am just kidding though, but that's what it feels like. There is also water cooling which might be a good choice and get even pricier.
You will not only need a powerful power supply, which also costs some extra money, but also a good electricity bill will come at your door. This depends where you live though and it is not that frightening, but there are cards with 300W+ and that's quite hefty if you really think of it. Unfortunately, there are times where the watt/performance ratio is really bad so you should stay up to date with the latest tech.
5. No need
Actually, if you don't have a good processor, a good power supply, three monitors, the new high end card will be as good as a mid range card. I personally have a 6770HD which is the same as a 5770HD (rebranded) and I can play every single game out there in Full High Definition. There are times where I have to switch off anti-aliasing, but that is something you won't notice from 2x to 8x, unless you have a lot of monitors. The cpu you might have, might bottleneck the card which is a very bad thing and you really don't want that to happen.
Keep in mind that those suggestions might apply to computers which are not so up to date and there is no need to upgrade the GPU. I hope this stuff comes to mind before trying to buy a new card and next time, if you have a 24" monitors just like me, don't grab a high end card, since it will not always be your best bet. If you are doing 3D stuff, then a switch to Nvidia Quadro or AMD FirePro is certainly the best choice.
Another last thing to keep in mind, is that a lot of GPU specifications are not always the same as you learn. They are usually theoritical and that is very important, in case you are about to choose only because of that. Usually a 2x bandwidth, in real life applications, is like 1.3x-1.7x better. If you want to spend a less as possible, buying an old generation card will certainly be the best choice, or you can buy a used graphic card, around forums.Discuss more on the forums
